Languages of Wikipedia

This map should be interpreted with caution for a few reasons. First, it only displays content from six Wikipedias (there are currently 282 of them). Second, many articles in multiple languages appear...
in the same place. The reason for this is that they are articles about the same feature, event, or place: albeit in different languages. This means that when mapping those features, the dots in each language will show up on the map in exactly the same place. As such, we get a lot of overlapping dots. And dots that higher up in the legend will then necessarily show up on top of others.
